Rick, after having built a couple dozen Buff horns over the years and owning 3, I've experimented with finish, buffler has it's own characteristics, to me it's much more grainy, by that I mean the layers of hair are rougher and not as tightly compacted as cow horn, when it starts to dry out the top layer starts to turn an ashy grey (kinda like my hair) lol, and will eventually start to look like what you statred with if it was a raw horn, I've tried a sealer on it, slowed this process down, but still drys out, I've tried paste wax on, same results, the last one I made for me, a year and a half ago I left unsealed and have just been keeping it moisturized with natural products and it looks like the day I finished it, I've been using lanolin, now I had an old time horner, Harold Moore tell me this, when oiling or conditioning anything natural use animal to animal, lanolin, bear grease, pig lard whatever, stay away from any petroleum or silicone products, so far it's been working for me, your mileage may vary!
